Mclaren 600LT Diffuser Carbon Rear Bumper 13AB611RP

the part number 13AB611RP refers to the Upper Rear Bumper Surround (often called the “Bumper Skin” or “Upper Diffuser Surround”) for the McLaren 600LT.

This specific component is part of the aggressive rear aero-cluster that defines the “Longtail” look, framing the top-exit exhaust and the massive rear diffuser.

1. Technical Identification

• Position: Rear Upper (encircles the exhaust exits and the rear mesh).

• Material: Typically Visual Carbon Fiber (Gloss or Satin finish).

• Design: It features the characteristic 600LT “cut-outs” for the top-exit exhaust pipes. It works in conjunction with the lower diffuser (which is a separate, larger piece) to channel heat and air away from the engine bay.

• The “RP” Suffix: In McLaren’s system, the .RP often indicates a Replacement Part or a specific revision within the Carbon Program, ensuring compatibility with the 600LT’s unique heat-shielding requirements.
